We are still in love with our recently purchased orig. owner 300CD, but we're finding a few of the same water/leaking issues. After reading over past threads, I see two possible reasons why our right rear floor gets so wet, but I wonder about a couple of *other* possible causes that I see on our car.<br>
<br>
Already identified possible water sources:<br>
1)windshield/screen gasket channels water<br>
2)w123 chassis rusts below seat bolts<br>
<br>
What I see:<br>
3)the interior and outside seals around the windows seem to have shrunk, leaving a perfect 0.5' gap right at the top of the window,<br>
4)there's a 1-2' rust spot in the bottom of the rt door. could water come down the window, past the cracking gasket, inside the door, and down to the floor?<br>
<br>
How do others deam with these problems?

I've got a 240d and the last storm left 3 gallons of water in my right back seat!!! (The car was parked sideways on a hill). I had a lot of ruined stuff, and my cars starting to smell funny. My door and windows seals are definitely not in good condition, but I suspect water must also be coming from somewhere else. Gonna check those seat bolts.<br>

Ive got a '81 ce with a suspect rear winshield gasket. Ive had this problem in old BMW 2002's as well. I have fixed it temporarily by applying a bead of silicone around both edges of the rubber gasket. Trouble here is that I think I have a little rust just Under the gasket. This rust needs to be removed not only to stop the rust from speading but to allow proper seating of the gasket. Does anyone know if this gasket can be replaced by some one who has never done auto glass before? special tools? Thanks!<br> <br> -jante

Sun Roof Drains

Don't overlook the Sunroof drains. There are 4 drains, one in each corner. It's not uncommon that one of the drains are cloged and leaking.

closing in

It's been almost a year since we got our 300 CD and we LOVE it. Of course, our mechanics in DC love us, too. While it's in excellent shape, there's always a new rubber piece that needs replacing. I guess 17 years is the lifespan of most rubber bushings and seals...

Anyway, we have narrowed down our leaks to the rear window seal, the trunk seal, and/or ??

Water sometimes soaks the rear floor RIGHT at the hump covering the driveshaft, but nowhere else. This can happen even when the car isn't driven, so it's not coming from below. Very intriguing.

I have the same problem on my 300 tdt, a lake back there... I think my problem is caused by some rusted holes by the drain in the engine room. I had one big hole welded right by the hood spring some weeks ago, and I´m having another one welded this Wednesday, the new one inside between the passenger seat wall and the wheel somewhere.

Try to hose your drains and see...

Any solutions to the leaks???

It seems that this particular leak is a very common issue with the 300 as it appears in many posts. Some of you guys recommend cleaning the sun roof drains out. If the headliner has no water stains, could it still be the sunroof? And did cleaning out the sunroof drains stop your leak? How many have found it to be their door seals? I'm really curious as I've found a 300D with the same issue, except that the left rear passenger foot well is flooded with water. I'm hoping that the leak can be stopped easily and without causing water damage to the car because I like this particular car and would like to purchase it.
